How do you rate a laugh - by its length, pitch, loudness, or a combination of all three? Well, researchers at Kansai University have successfully developed a device that can measure the quantity of a human's laughter while filtering through real and fake laughter. Currently, laughter quantity is known as "aH", where a single second of explosive laughter results in 5 aH. This system is smart enough to tell between fake and real laughter by monitoring the diaphgram's movement. Should a person fake his'her laughter, this machine is able to detect that the diaphgram did not vibrate, in stark contrast to what a real laughter can muster. The researchers are currently working on a portable version that can be used in health and entertainment devices. Guess live sitcom recordings will never be the same again with this device.
